Comedian Jim Davidson is one of two men arrested earlier on suspicion of sexual offences, the BBC understands.
Officers from the Met Police's Operation Yewtree - set up in the wake of the Jimmy Savile scandal - arrested Mr Davidson, 59, in west London.
A 53-year-old man was also arrested at 08:00 GMT and taken into custody locally in Hampshire, the Met said.
Scotland Yard said the arrests were not connected to the allegations made against the late BBC presenter.
Mr Davidson presented long-running BBC One shows Generation Game and Big Break.
His break came in 1976 when he won TV talent show New Faces, he hosted his own TV show The Jim Davidson Show, and has had continued success as stand-up comic.
He was appointed an OBE in 2001 for his services to charity.
Operation Yewtree is the Met's investigation into allegations, some dating back decades, that have arisen since Savile was accused of abuse.
The operation has three strands.
One is looking specifically at the actions of Savile and the second strand concerns allegations against "Savile and others".
The third strand, under which the two men were arrested on Wednesday, relates to alleged complaints against other people unconnected to the Jimmy Savile investigations.
These men are the ninth and 10th to be questioned as part of the police operation.
Savile, who died in 2011 aged 84, was a BBC Radio 1 DJ and the presenter of the Jim'll Fix It show on BBC One. The police say 450 victims have alleged abuse by Savile alone.
